Specification of Letters Patent.

Patented May 1, 1906.

Application led October 2,1902. Renewed September 30, 1905. Serial No.280.831.

To all whom t may concern:

Be it known that I, GEORGE E. WHITNEY, a citizen of the United States,residing at Boston, in the county of Suffolk and Commonwealth ofMassachusetts, have invented an Improvement in Stung-Box Adjusters, ofwhich the following description, in connection with the accompanyingdrawings, is a speciiication, like letters on the drawings representinglike parts.

My invention aims to rovide an improved form of adjustable st ng-box bymeans of which any desired adjustment of the glandretaining member ofthe stufling-box may be effected in a simple, convenient, andexpeditious manner. i

My invention will be best understood from the description andaccompanying illustra-` tion of one specific embodiment thereof, whileits scope will be particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a sectional view through theadjusting member -on the dotted line 1 1 in Fig. 2 looking upward at theengine-cylinder head and the attached stuffing-box. Fig. 2 is a centralsectional elevation on the dotted line 2 2 in Fig. 1 through thecylinder-head and stuffing-box.

In the drawings, a represents a cylinderhead of any suitableconstruction provided with a piston-rod stufling-box b, formed in thepresent instance for convenience in construction in a removable memberc, which is threaded into the inner side of the cylinderhead againstashoulder formed thereon. This stung-box is provided with the usual glandd and is retained in any desired position within the stufling-box by theadjustable member e, adapted to engage with the externally-threadedportion of the stuffingbox member c and having the retainingshoulder eadapted to engage With the gland d and force the same against thewithin-contained packing. The threads upon the two engaging members aresufficiently fine to afford the required delicacy of adjustmentcorresponding to any angular movement of the adjusting member.

The means by which I effect the movement of the adjusting member toproduce any desired adjustment comprises the laterallyproj eotfng memberor lever f slidably held in operative relation to the adjusting memberin any desired way so as to be capable of radial movement-as, forexample, by a suitable holder or carrier, which herein consists of thetwo plates f and f2, forming a recess for the reception of the lever f.The plates f and f2 are suitably formed so as to encircle the adjustingmember e and may be rotated about the same and are fastened together inany desired manner so as to embrace between them the teeth e2,projecting laterally from the said adjusting member and bring intoadjustment therewith the toothed proj ection f 3 on the lever f, wherebythe latter is adapted for coperation with the recessed portions betweenthe teeth c2 on the adjusting member e. In the lever f at that portionWithin the recess formed by the plates f and f2 is formed a shortlongitudinal slot f4., containing the spring f 5, bearing at one endagainst the stop f 6, secured in the plates f and f 2 and normallyforcing the toothed portion of the lever f into engagement With some onerecess on the adjusting member e, but affordin a sufficient outward orradial movement for the lever when the spring is compressed by anoutward or radial pull upon the end of the lever as to permit thelever-toothf3 to clear the peripheral line of the tee'th on theadjusting member-as, for example, is shown in the superimposeddotted-line position in Fig. 1. When the spring is compressed in thismanner, the lever may be moved through any desired angle affordingan'unobstructed path for the same, the plates f and f2, which carry thelever, being freely rotatable about the adjusting member, but preventedfrom axial movement thereupon. In the drawin s I have shown anunobstructed path of angular movement for the lever f from the positionshown in Fig. 1, where it rests against the portion g of theengine-framework in a counter-clockwise direction, to the position Whereit would contact with the portion g of the engine-frame; but anysuitable or desired stop to limit the angular movement of the lever maybe provided where desired.

The'operation of the device is as follows: If it is desired to compressthe packing material Within the stuffing-box, the spring f5 is IOOcompressed by an outward pull upon the lever until the latter isdisengaged from the teeth of the adjusting member. Assuming the threadsupon the adjusting member to be right-handed, the lever is rotated in alefthanded direction to the limit of its movement if the full limit ofadjustment is desired or to a correspondingly lesser extent-as, forexample, the lever position shown in dotted lines at right angles to thefull-line positionifa lesser adjustment is desired and the lever broughtinto engagement With the nearest recess on the adjusting member byrelieving the same of the radial pull. The lever is any desiredoperating-point which convenience may dictate, and it may be itselfadapted for manipulation or may be combined With other hand-operatedmembers and receive movement therefrom. After the adjustment has beeneffected the lever may be returned to a position of engagement incontact with a stop or abutment-such as g, for example-and provided insuch position a locking means to prevent the adjusting member frommoving in a reverse direction and Working loose.

The lever f constitutes a manipulating member removed from the oily ordirty parts of the engine or the moving parts thereof and affords ameans for adjusting the stuflingbox in a simple andyrapid manner.

It Will be evident that my invention is not limited to the specific formof construction shown, Which is submitted for illustrative purposesonly, but that it may be embodied in a great variety of forms, all ofWhich are Within the scope of my invention.

I claiml. The combination of a stuffing-box, a gland', a threadedadjusting member therefor, a radially-extended operating member to causemovement of said adjusting member and a holder therefor.

2. The combination of a stufling-box, a gland, a threaded adjustingmember therefor,

an operating-lever connected with said adjusting member for moving thesame by an angular movement thereof about said stuing-box and a holderfor said lever.

3. The combination of a stuffing-box, an adjusting member therefor, andoperating means for said adjusting member adapted to be moved coaxiallytherewith either in or out of engagement with said adjusting member.

4. The combination of a stufiing-box, an adjusting member therefor,operating means capable of independent movement thereof for effecting amovement of said adjusting member, and adapted Within its path ofmovement to engage said adjusting member in a plurality of positions andholding means for said operating means.

5. The combination of a stuffing-box, an adjusting member, operatingmeans for moving said adjusting member adapted for engagement with anddisengagement from said operating member and capable of independentthough guided movement during periods of disengagement.

6. The combination of a stuffing-box, an adjusting member swinginglymounted, operating means normally in engagement with said adjustingmember for moving the same, and means to release said operating meansand engage the adjusting member in a different position.

7. The combination of a stuffing-box, an adjusting member, a laterallyextended sWingingly-mounted operating-lever in engagement With saidadjusting member for moving the same, and means to release saidoperating-lever and engage the adjusting member in a different position.

8. The combination of a stuffing-box, an adjusting member therefor, alaterally-extended operating-lever for moving the same, means forengaging and disengaging the same from said adjusting member and aholder for said'lever.

9. The combination of a stuffing-box, an adjusting member therefor, anoperating member having an operating movement for moving the same,coperating locking parts upon the operating member and adjusting member,and means to engage the adjusting member by the operating member in aplurality of positions said operating member When unlocked having amovement similar to its operating movement.
